17 Claims. (CI. 16-158) This invention relates to a hinge, more particularly to a hinge of the type comprising two hinge members each of which comprises a bail having a sleeve portion defining the hinge axis and two side portions extending transversely of said sleeve portion and adapted to be fixed to one of the two parts to be connected by the hinge.

It is an object of the invention to provide a hinge member of the type described, which can be fixed to said part without nails so as to efiectively resist the working load imposed thereon for a practically unlimited time without becoming slack.

It is another object of the invention to provide a tool for fixing and removing such improved hinge member.

It is a further object of the invention to provide a hinge comprising two hinge members connected by a hinge pin and separable without requiringthe hinge pin to be removed substantially from the hinge.

. 2 bosses, spikes or the like, which may be formed most simply by bulging the side portions at those points where they are to be formed with depressions on the inside.

It is another object of the invention to provide a hinge I of the type described, in which a fixing strip arranged between the side portions of the bail is formed with apertures facilitating the movement of the strip and accessible without requiring apertures in the wooden parts in which the hinge is inserted.

It is a feature of the invention to provide a hinge member comprising a bail having a longitudinally extending sleeve portion defining a hinge axis, and two side port-ions adapted to be received in a groove formed in a part to which said hinge member is to be fixed, at least one of said side portions being formed on its inside with several surface irregularities distributed throughout the length of said hinge member, and a fixing strip interposed between and engaging both said side portions and movable relative thereto in the longitudinal direction of said hinge member, said strip being formed with surface irregularities adapted to register in an initial position of the strip with the surface irregularities in said bail and to spread said side portions apart to cause them to be held in said groove upon a movement of the fixing strip from said initial position in the longitudinal direction of said hinge member.

It is another feature of the invention to provide a hinge comprising two bail-like hinge members each of which comprises a plurality of sleeve portions aligned in alternation with the sleeve portions of the other hinge member to define a hinge axis and two side portions adapted to be fixed to one of the two parts to be connected by the hinge, and a'plurality of hinge pin parts having crowned ends and a length equal to that of said sleeve portions, each of said hinge pin parts being received by two adjacent sleeve portions of saidhinge members.

. To facilitate the movement of the fixing strip between the side portions of the hinge member the surface irre uliarities in the bail and/or the fixing strip are preferably formed with lateral surface portions which are inclined relative to the plane of the bail or strip. The surface irregularities may consist of elevations or depressions and it is ofpspecial advantage to provide the out- Figs. 13 and 14 illustrate the displacement of the 'fixi'ng strip by means of an appropriate tool, in two difierent positions.

Figs. 18 and 19 are fragmentary sectional views taken along lines XVIIIXVIII and XIX-XIX, respectively,-

Figs. 21 and 22 are an elevation and side view,'re-" spectively, of a tool serving to move said fixingfstrip; In the embodiments shown in Figs. 1-14 the hinge com prises two bail members formed by bending a strip, around the hinge axis. Thus each hinge member comprisestwo fiat side portions 1, 1', which are bent around thehinge pin 2. Between the two side portions 1 and 1' a fixing strip 3 is arranged, which is movable in the longitudinal direction of the hinge. The side portions are provided at one end with a lug 4, bent at 90 deg., for limiting-the longitudinalmovement of the fixing strip when it is intro} portions 1 and 1' are provided with a series of boss lik e elevations 5, which, lie on an imaginary straight line side of the side portions with elevations in the form' of 1 parallel to the hinge axis. The drivingofthe bosses, 5

causes the formation of corresponding depressions 6"ontheinside of .side portions 1 andl. The fixing strip 3' is formed with depressions 8 and bosses 7 corresponding to the bosses 5 and depressions 6 in the side portions l, 1. Figs. 4 and v5 show that the surface. irregularities 5, 6, 7, 8 in the side portions 1, 1 and in the fixing "strip 3 compriselateral surface portions which are inclinedto,

the plane of the respective sideportion or strip." In initial position of 'the strip 3 shown in Figs. 4 and' 6, th e bosses 7 enter the depressions 6 and the sidepor'tions 1 and 1' are spaced only by the thickness of thei'interposed fixing strip 3. I i The side portions of the bail members are inserted in grooves 29, which preferably extend from-edges of-tlie bosses.

a t two parts that are to be connected by means of the hinge into the interior of such parts. However, the grooves may alternatively extend at right angles. from one of the limiting surfaces. Thus. a perfectly tight connection of saidtwo parts can be achieved. Moreover, such grooves can be milled easily. W11en the fixingstrip .3 is now moved in the longitudinal direction, the two side portions I and 1' are spread apart and the bosses 5 are forced against the walls of the groove 29 (Fig. 7). Owing to the high static friction. the'grooves 29 can be formed not only in parts of wood, but also in members of stone, metal, etc.; the hinge will remain perfectly in position also in the lastmentioned materials after the fixing strip has been displaced. In the case of soft timber, milled grooves 29 bounded by two parallel walls are sufficient for hinges according to Figs. 6 and 7. In that easev the bosses 5 will. be forced sufrl' ci ently into the wood after the two side portions land 1' have been spread apart. Where hard wood or other substantially hard materials and hinges having bosses on the outside are used, it is suitable to form the material with grooves 30, which maybe shallower than the The fixing strip 3 can be displaced in different ways.

As indicated in Fig. 4, the strip 3 can be driven in between the sideportionsl, 1'. In that case the hinge member remains either permanently in the wood or a similar strip must be driven in from the other end deep enough to move the strip 3 back into its initial position, shown in Fig. 4, to enable the removal of the hinge member which can then be pulled out easily. It is more suitable, however, to provide apertures in the side portions 1 1' and in the fixing strip 3, as is indicated in Fig. 1 on the right. In that embodiment each of side portions 1, 1 has an intermediate aperture 9 and two lateral, longer apertures '10. r The fixing strip 3 is formed with a longer intermediate aperture 11 and two short lateral apertures 12. 'As is shown in Figs. 6, 12 and 13, an oblong aperture 14; through which a tool 15 can be introduced, is formed in the wood 13. 'The tool 15 comprises suitably a fixed jaw. 16 withaprojection 17 to be received in aperture 9 or 11, and a lever 19, which is pivoted at 18 to the fixed jaw 16 and has a cam end 20 engag ing a sliding piece 21, which has also a projection 22 to be received in the lateral apertures and .12.

When according to Fig. 13 the tool is introduced into the intermediate and right-hand apertures of Fig. 1 and the jaw 16 and lever 19 are forced together, the sliding piece 21 will move to the right to take the fixingstrip 3 along in the same direction until the latter has assumed the position shown in vFig. 5. t

. .When the tool is reversed and introduced according to the apertures which are on the left and at the center in Fig. 1 and the jaw 16 and lever 19 are again forced, to-

gether, the slidingnpiece 21 will be moved to the left so Y that finally the fixingstrip 3 will again assume its initial position, shown in Fig. -4 Then the two side portions land 1 are no longers pread apart and the hinge member can easily be pulled out of the groove '29.

It is not necessary, however, toprovide three apertures 9-12 because two of them are sutficient. In that case it is necessary, however, to force thejaw and the lever of the tool apart for'removing the hinge. In any case the fixing strip 3 is formed with an aperture 12 which has two edges 12 and 12" extending transversely of the longitudinal direction of the hinge member, whereas each of the side portions 1, 1 isformed with an aperture It) registering with said aperture 12in the fixing strip and exposing at least one of the edges '12'.and. 12" to enable the same to be engaged for moving ,said strip. I

Where two longitudinally spaced ,sets of registering apertures are provided, .one of said sets may comprise a relatively long aperture 10 in each of the side portions 1, 1 and a relatively short aperture .12 in'the fixingqstrip, whereas the otherofsaid sets'imay comprise a relatively asaaaor 4 long aperture 11 in the fixing strip and a relatively short aperture 9 in each of the side portions 1, 1.

j Whether the two sets of apertures described above are provided or the three sets of apertures shown in the drawing, each of the relatively short apertures 9, 12 has two edges, designated 9'," 9" and 12, 12", extending transversely of the longitudinal direction of the hinge member and the length of the relatively long apertures 10, 11 is at least equal to the spacing of the transverse edges of the relatively short aperture of the same set plus the displacement a of the strip 3 required to move it from its initial position sufficiently to spread the side portions 1, 1 apart.

.The relatively long apertures 10 in the side portions expose at least one of the transverse edges 9', 9" of the fixing strip to enable said edge to be engaged for moving the strip.

The embodiment shown in Figs. 8-11 differs from that shown in the other Figures only by the provision of spikes 230m the outside of the, two limbs 1 and 1. The side portions 1, I. themselves have no elevations but only depressions 24, with which elevations 25 formed in the fixingstrip 3 are in register in the initial position of the strip (see Fig. 10). When the fixing strip 3 is displaced, the elevations 25 are moved out of the depressions 24 to spread the two side portions 1 and 1 apart.

To enable the easy disconnection of the two members of the hinge even after they have been mounted, and to facilitate their manufacture, the hinge pin is suitably made up of a plurality of parts 26 which have crowned ends and are accurately of the same length as the several sleeve portions 27 and 28. In the position for use the adjacent pin parts 26 engage one another at the center'ol: the sleeve portions. length, e. g. by driving in a bolt or the like from the outside, they are located only in their associated sleeve portion and'the two hinge members can be separated Without dilficulty. To reconnect the two hinge members, the bolt is driven in sufficiently to move the several pin parts 26 by half the length of a sleeve portionj I Particularly in the case of long hinge members it may be suitable to form the fixing strip 3 not as a single piece but, as is shown in Fig. 12 in several parts 3, 3" spaced by the distance a through which the several strip parts are to be displaced. In that case the displacement of the several strip parts 3, 3 does not require a force as large as that necessary for moving a strip of the entire length by means of the tool. It is obvious that the apertures such as 9-i2 which are necessary to enable the movement of the strip, must be formed in each of the strip portions .3, 3" and in the adjacent areas of the side portions 1, 1.

The surface irregularities, i. e. the elevations and/or depressions can be formed inany stage of the manufacture of the hinge members. It may be of special advantage to roll them already into the sheet metal from which the hinge members are formed; the same applies to the bending lines 31 and 32 limiting the transition parts between the sleeve portion and the side portions to be spread 1 apart (see Fig. 6), and/or the spikes 2'3 and the apertures for receiving the respective other hinge member. In that case the preformed sheets can be bent around corresponding "hinge pins to form the hinges.

Like the embodiments described hereinbefore, the hinge member shown in Figs. 1-520 comprises a bail having a tubular sleeve portion defining the hinge axis, and two sideportions 41, 41 extending transversely of said sleeve portion '40 and adapted to be received in a groove 29 formed in a part to which said hinge memberis to be fixed. As in the embodiments shown in Figs. l-l l, a fixing strip 43 is provided, which is movable in the longitudinal direction of the hinge member. .The fixing strip 43 is formed on both sides with two rows of surface irregularities, which may be considered elongated bosses .45 and 45 orcorresponding depressions .46 and ,46",f depending on the side'from which the strip is viewed. The

If they are displaced by half their side portions 41 and 41 are'formed with apertures 48 adapted toregister with the outer row of bosses 45. The apertures 45 are formed with-sharp-edged, raised rim portions 47, which will be forced 'into the wood or the like when the two side portions are spread apart. For a purpose which will be set forth hereinafter the rim portions 47 have axially outwardly tapering outer peripheral surfaces. In the region of the inner row of bosses 45' the side portions 41 and 41' are curved to form on their inside a recess 47, extending parallel to the hinge axis and receiving the inner row of bosses 45 for guiding the strip 43, which is thus mainted parallel to the hinge axis.

Each of the strips 43 is formed with an aperture consisting of-a marginal recess 51, which has two edges 51, 51 extending transversely of the longitudinal direction of the hinge member and adapted to be engaged for moving the strip 43. For this purpose a tool is provided, which consists of a plate 55 formed with a projection 52 (Figs. 21 and 22). The sleeve portion 40 of each hinge member is formed'adjacent to the recess51 with'a slit 49, which is long enough to permit of the movement of the tool 55 whose projection 52 has been inserted through the slit 49 into the recess 51, and thus of the movement enable the insertion of the projection 52 of the tool 55 through the slit 49 into the recess 51 the hinge pin means 42 accommodated in the sleeve portions 40 of both hinge members leaves free the lengths in which said sleeve portions are formed with said slits 49. To this end the hinge pin means may comprise two separate parts, each of which is accommodated in the sleeve portions 40 of both hinge members and which are arranged toleave free between them the length in which said sleeve portions are formed with the slits 49 andthe length between the slit 49 in one sleeve portion and the slit 49 of the other sleeve portion. Fig. 20 shows the slit 49 to be covered completely when the hinge is closed. Thus the slit does not disturb the appearance of the hinge. As is apparent from Figs. 17 and 22 the slit 49 is displaced from the fcenter' plane of the hinge member so that the slit is not accessible when the door or the like is closed. Thus an unauthorized disassembly of the hinge is prevented ment of the slit 49 the projection 52of the tool 55 is slightly curved.

To fix the hinge member in position after it has been inserted in the groove 29 the fixing strip 43 is moved from its initial position, in which the bosses 45 are received in the apertures 48, sufiiciently to move the side portions 41, 41' apart. To this end the-projectionSZ is inserted through the slit 49 into the recess 51 of the strip 43, Whereafter the latter is driven to the left by slight blows on the plate 55 until the projection 52 engages the end of the slit 49. Thus the side portions 41and 41' are spread apart and the sharp-edged rim portions 47 penetrate into the wood or the liketo fix the hinge member against lateral and longitudinal displacement.

To remove the hinge member, the projection 52'of the tool 55 is again inserted into the recess 51 and is displaced in the opposite direction until the bosses 45 register with the apertures 48.- Now the hinge member is readily removable, the rim portions 47 sliding out of their anchoring material along their tapered outer peripheral surfaces (Fig. 17). H

The length of the slit 49 in the bail is at least equal to i the spacing of the transverse edges 51', 51" of the marginal recess of the strip 43 plus the displacement a of the strip 43 required to move it from its initial position sufliciently to spread the side portions 41, 41'japart.

Thus the slit 49 will expose in any position of the strip 43 at least one of the transverse edges 51', 51" to'enable said edge to be engaged for moving the strip.

Each of the hinge pin parts 42lshown in Fig. 15may be considered constructed like the hinge pin '26 of Fig. 1.

In accordance with the arrange In that case the mutually opposite ends of the slots 49 are preferably arranged at the longitudinal center of the respective section of the sleeve portion in which they are formed and are thus spaced apart by the length of one such section of the sleeve portions. In that case the hinge can be taken apart after the two hinge pin parts 42 normally terminating at said mutually opposite slot ends have been displaced to meet at the junction of the two slotted sleeve sections.

In all illustrative embodiments shown, similar surface irregularities in the side portions of the bail are spaced in the longitudinal direction of the hinge member bya of the transverse edges 9', 9" or 12, 12" of the corresponding short apertures in the fixing strip 3 or side portions 1, 1' or of the transverse edges 51', 51" of the fixing strip 43.
